FIGURE 2.

Abscission in fonio, cranberry, grapes, and tomatoes. (A–F) Images of fonio illustrating the developing plant (A), a mature inflorescence (B), and scanning electron micrographs of the abscission zone of a mature seed (C–F). (G–I) Images of cranberry illustrating the developing fruit (G) and sections revealing the fruit abscission zone (H,I). (J–L) Images of grape illustrating a fruit cluster (J) and sections revealing the fruit abscission zone (K,L). (M–Q) Images of tomatoes illustrating the abscission zones in tomatoes. A variety of cultivars were observed and pictured are two cluster varieties: Principe Borghese (M), and Ladybug (N). (O–Q) Illustrate freehand sections of the pedicel abscission zone attached directly to the developing fruit. Black and white arrows show fruit/pedicel abscission zones and red arrows show the “knuckle” abscission zone.
